The European corn borer (Ostrinia nubilalis), also known as the European corn worm or European high-flyer, is a moth of the family Crambidae. It is a pest of grain, particularly maize ( Zea mays ). The insect is native to Europe, originally infesting varieties of millet , including broom corn .
The European potato failure was a food crisis caused by potato blight that struck Northern and Western Europe in the mid-1840s. The time is also known as the Hungry Forties . While the crisis produced excess mortality and suffering across the affected areas, particularly affected were the Scottish Highlands , with the Highland Potato Famine and ...
The Asian corn borer, Ostrinia furnacalis, is one of the biggest pests of maize in Asia, causing 10%-30% of yield losses in the field, and in some cases up to 80% yield loss. [7] These pests carry fungal pathogens (such as Bipolaris maydis and Curvularia lunata ) which cause diseases such as maydis leaf blight and curvularia leaf spot in the crop.
This was the 'New Leaf' potato, and it was removed from the market in 2001 due to lack of interest. [59] In 1996, genetically modified maize producing Bt Cry protein was approved, which killed the European corn borer and related species; subsequent Bt genes were introduced that killed corn rootworm larvae.

Diabrotica undecimpunctata, the spotted cucumber beetle or southern corn rootworm, is a species of cucumber beetle that is native to North America. The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle.
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology. GDD are a measure of heat accumulation used by horticulturists , gardeners , and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
Trichobaris trinotata, commonly known as the potato stalk borer, is a species of weevil in the family Curculionidae. [ 1 ] [ 2 ] It is found in North America where it is a pest of potato plants, the larvae tunnelling inside their stems.
There is an inserted gene in the DNA of MON 810 which allows the plant to make a protein that harms insects that try to eat it. The inserted gene is from the Bacillus thuringiensis which produces the Bt protein that is poisonous to insects in the order Lepidoptera (butterflies and moths), including the European corn borer.
